Application Adjustment
time
Floor heating and other static heating surfaces 10 - 30 min.
Radiator heating 6 -10 min.
Convector heating 3 - 6 min.
7.3.4.10.1.3 Sample time Ta
The sample time is a controller-internal value which defines the
time interval between two subsequent actuator pulses in the
presence of a control deviation. Shorter sample times allow finer
adjustments.
7.3.4.10.1.4 Actuator runtime
This function allows adjustment of the actuator, with regard to its
finite runtime, to the control characteristics, meaning that
actuators with different runtimes (e.g. 1 min., 2 min., 4 min.) react
to the same deviation by readjusting by the same amount through
adapting the action times. The integral action time Tn remains
unchanged here. However, care must be taken that the latter
must always exceed the runtime of the respective actuator. If
necessary, actuators must be used with other runtimes.
